Is C# development still tied to Windows? It's been a very long time since I looked and I’m curious what people's preferred development environment is…?
Today, I wasted 2 hours debugging what I thought was very odd behaviour in #csharp until I learned that async Task and async void are two very different things, and now I am very angry about async void. Was about to ban its usage entirely, but this SO article was helpful in explaining how it can be useful and not just a foot-gun
Stay updated with the latest network programming knowledge in #CSharp and #DotNet! 📚 Check out the new RSS feed for "Beyond Boundaries - Networking Programming with C# 12 and .NET 8" for tips, updates, and expert insights.
This is detailed, step-by-step instructions of getting this set up, with screenshots to help with commands and outcomes. An "idiot's guide" if you like, because I was that idiot.
For the performance, sure, maybe, depending on the situation, but for readability, I find collection.Any() more readable than collection.Count() > 0. #csharp#dotnet
I'm working on chapters 7 and 8 of the C# Networking Book. I hope to have Chapter 7, Data Serialization Techniques, out early next week and Chapter 8, Network Performance Optimization, out the following week.
With Chapter 8 finished, I will have the basics done.
Excited to unveil the latest chapter in my C# book on Error Handling and Fault Tolerance Strategies! Dive deep into advanced techniques to elevate your network programming, ensuring your systems and applications are more resilient and user-friendly. #csharp#dotnet#networkdev
I’m hosting Chris Simon on a #JetBrains#livestream to discuss #TDD, #DDD, and #csharp. Not to be confused with D&D, which is about wizards, dragons, and dungeon masters… wait it's pretty similar.
Hm is it me or there is some sort of obsession to constantly update a programming language to fill it with "stuff" and "features"
I'm noticing a clear trend for this in #csharp and #cpp, but I'm sure there are others
I mean people keep asking why C is still widely used. I'm pretty sure that one of the reasons is that the spec has barely changed in 50 years or so and it works
C'mon some programming languages are fine as they are, please don't keep crowding them unless absolutely necessary pls?
@glitchypixel You can pretty much use C++ like we were living in 1998 if you please, and that's pretty cool. But in the meantime the additions make it possible to write the same programs more efficiently with better performance and safer too, and that's even cooler.
@asperamanca@glitchypixel this. I get that "the way you write programs becomes obsolete every three years" is frustrating, but at least C++ remains backwards compatible. Like you said, you can still code like it's 1990 if you really want. And all those old libraries also still work.
The "Collection was modified" inspection in #ReSharper is quite handy. Warns you about those accidental collection updates while looping over them, resulting in a runtime error. And can fix them automatically! #csharp#dotnet
@lostprototype You can download and install FLCC in Rider but the C# model is still being fine-tuned, so results may vary. That’s why we said “coming soon”, we’re not ready to say that it’s ready.
I would argue that Entity Framework Core (#csharp#dotnet) has the same pros and cons like any other ORM no matter what language.
Those ORMs looking appealing at first, but once you start doing more advanced things, they start to get in your way and getting slow.
Instead I use ADO.NET (Npgsql), Dapper and Fluent Migrator. Having the ability to write your queries in plain SQL and using Dapper for object mapping matches they way I do it in #php
I want to see if it's possible to replace runtime reflection in @xunit v3 with #Roslyn source generators (for better performance and to support NativeAOT), but I think I've already hit the first blocking point: no support for #FSharp? Only #CSharp and #VB? #dotnet
@bradwilson@xunit instead of Roslyn source generators you can have a regular MSBuild code generator that generates code during the build, and it can be any code and support C# and F# equally well. I often find that people use Roslyn source generators when all they want is any code generator.
I have written C# top-level code before, but I'm obviously suffering a "brain freeze" right now: Why does this simple top-level C# statement say "The name 'Console' does not exist in this context", even though I'm compiling with .NET 7.x and .NET 8 (well past .NET 5 that top-level statements need)? 😳
Console.WriteLine("hello world"); //System.Console works
@khalidabuhakmeh Indeed. Neither .NET Fiddle nor Compiler Explorer support implicit usings. IIUC they'd have to explicitly disable implicit usings, and that perplexes me. But then maybe Implicit Usings is somehow VS specific and that's how they aren't in place. 🥺
Too bad, I was hoping to make 101 course examples, and offer a playground, as simple as possible. But the ceremonial "using System;" line will have to get into code.
